it's not just about windows defender becoming decent (although that's certainly a prerequisite). the motivations are more aligned in favor of users when OS providers are also the AV providers. an OS provider wants viruses to be eliminated, because they harm the OS' reputation. a third-party AV provider wants viruses to continue to be a problem, because consumers' fear of viruses drives their revenue. all other factors being equal, if i'm using a microsoft OS, i want a microsoft AV.
